Abstract

The correlation between physical and chemical attributes of fruits can serve as indicators for the ideal harvest time and function as selection criteria to enhance the management and productivity of crops. This study aimed to investigate the correlations among physical and chemical properties of Cortibel guava fruits grown in the Brazilian Cerrado. Parameters assessed included skin and pulp color, weight, diameter, length, total soluble solids, titratable acidity, and the ratio of these characteristics. Data were analyzed using Pearson's linear correlation with a significance level of P < 0.05. Several physical and chemical properties of the fruits exhibited significant correlations. The highest correlation coefficients were observed between weight and fruit diameter, as well as between hue angle of the skin and skin lightness. The properties of Cortibel guava fruits cultivated in the Brazilian Cerrado exhibit significant correlations. These findings enable the utilization of straightforward parameters in the selection processes of Cortibel guava for breeding objectives. Highlights: Guava is a significant crop with high economic value. The characterization of fruits assists in selecting genotypes with desirable commercial properties. Cortibel guava fruits exhibited significant correlations between some physical and chemical characteristics. The correlations between the physical and chemical characteristics of the fruits allow the selection of materials of interest for breeding.

巴西塞拉多地区番石榴果实理化特性的相关性研究

果实理化性状之间的相关性可以作为理想收获期的指标，也可以作为提高作物管理和生产力的选择标准。本研究旨在探讨生长在巴西塞拉多的科蒂贝尔番石榴果实的物理和化学特性之间的相关性。评估的参数包括果皮和果肉颜色、重量、直径、长度、总可溶性固形物、可滴定酸度以及这些特征的比例。数据采用Pearson线性相关分析，显著性水平P < 0.05。果实的几种理化性质表现出显著的相关性。果实质量与果实直径、果皮色相角与果皮亮度的相关系数最高。在巴西塞拉多栽培的可可番石榴果实的性状表现出显著的相关性。这些发现使得在可可番石榴育种目标的选择过程中使用直接的参数成为可能。番石榴是一种重要的经济作物，具有很高的经济价值。水果的特性有助于选择具有理想商业特性的基因型。科蒂尔番石榴果实的一些理化性状具有显著的相关性。果实的物理和化学特性之间的相互关系使人们能够选择感兴趣的材料进行育种。
